A transit cop was injured in a tussle with a couple of Brooklyn turnstile jumpers Tuesday afternoon, cops said.

The melee erupted at the E. 105 Street station in Canarsie around 12:15 p.m. when the man hopped the turnstile for the L train and two transit cops confronted him, according to the NYPD.

As the two cops were struggling with the alleged fare jumper, a woman entered the fray and one of the officers fell, slamming the back of his head on the ground, cops said.

The bleeding officer was taken to a nearby hospital, where he was expected to be OK.

The couple was taken into custody with charges pending Tuesday afternoon.

The arrests come amid a crackdown on fare beaters.
